Note(s): | The rpmF and pslX-fab genes are cotranscribed, and this is the fist example where lipid biosynthetic genes and a ribosomal protein gene comprise an operon Podkovyrov S,1995 It is probable that yceD-rpmF-plsX-fabHDG-acpP-fabF cluster genes are regulated together, since they are involved in the same functional class. However, a transcript that continues through the entire gene cluster has not been determined by Northern blotting or by experiments with polar mutations. |

Note(s): | The pslX transcripts were detected only by RT-PCR, and therefore the lengths of these transcripts are unknown. They could initiate at the promoters located upstream of g30k as determined by Tanaka Y,1989and/or at the fabH promoter mapped by Podkovyrov SM,1996CITS:[9642179]|. It is probable that yceD-rpmF-plsX-fabHDG-acpP-fabF cluster genes are regulated together, since they are involved in the same functional class. However, a transcript that continues through the entire gene cluster has not been determined by Northern blotting nor by experiments with polar mutations. |

fabH has a GC-rich motif discriminator sequence between the -10 region and the start site, which is a characteristic feature of the stringently regulated promoter Podkovyrov SM,1996 The fabH promoter is not only a contributor to its expression under all conditions, but also other activators might compensate to activate fabH expression when FadR is absent, and/or with basal expression of the fabHGD genes My L,2013 Evidence: |

Note(s): | acpP expression is not under growth rate control Zhang Y,1996. A consensus sequence resembling the FadR-binding site was identified at position -40 upstream from the acpP promoter Henry MF,1992. However, analysis in a gel shift assay of the acpP fragment containing the putative FadR-binding site compared to the purified FadR protein gave no significant shift of the DNA band, nor was there a significant change in acpP expression in a fadR null mutant strain. These findings indicate that FadR is not involved in the regulation of ACP expression Zhang Y,1996. |
